Much like the diet phenomenon Eat This Not That, this series aims to replace some common, existing teaching practices with approaches that are more effective—healthier, if you will—for our students. We hope to draw attention to widespread practices around important instructional topics that have little support in research or professional wisdom and offer alternatives that have greater support. Each text is collaboratively written by authors representing research and practice. By the end of each book, you will understand both what not to do, and what to do, to improve student learning.
